Hi folks, I’ve just added nuxt to my koa app, and I noticed an impact on my api test suite. It seems that solely by importing nuxt, Vue’s production tip is logged to the console.

Below is an isolated reproduction of the issue, and you can download it here.

const { Nuxt } = require('nuxt')

it('logs vue production tip', () => {
  console.log('done')
})

(note that it doesn’t actually render anything)

npm test

 PASS  ./test.js
  ✓ logs vue production tip (1ms)

  console.info node_modules/vue/dist/vue.runtime.common.js:7913
    You are running Vue in development mode.
    Make sure to turn on production mode when deploying for production.

  console.log test.js:4
    done

Any idea what’s going on here?
